How to compare multidimensional arrays in C# ?

Question

How to compare multidimensional arrays? Just true/false.

double[,] data1 = new double[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };    
double[,] data2 = ne         


        

Answer 1

A multidimensional array can be used in linq as one dimensional enumerable. You just need to check also for the length of all dimensions. This snippet should be enough:

var equal =
    data1.Rank == data2.Rank &&
    Enumerable.Range(0,data1.Rank).All(dimension => data1.GetLength(dimension) == data2.GetLength(dimension)) &&
    data1.Cast().SequenceEqual(data2.Cast());
